Cyclone III Device管脚使用推荐
gned to single-ended or differential I/O standards if it is being fed by a PLL output.
PLL[1..4]_CLKOUTn Note 3_____ Optional negative terminal for external clock outputs from PLL[1..4]. These pins can be assigned to single-ended or differential I/O standards if it is being fed by a PLL output.
两用配置脚:
nCEO_____this pin通过10-KΩ连接到vccio。
FLASH_nCE, nCSO _____此管脚为FLASH_nCE 当在AP模式下, AS模式下得时候为nCSO。
DATA1, ASDO_____ 在as模式下得时候functions as ASDO
CRC_ERROR_____如果不用再循环纠错中,可用作io啊。
DEV_OE_____看你用不用
INIT_DONE __通过10k电阻连接到对应的VCCIO上面。我的IO有2.5v的,有3.3v的,对应是3.3v的。
唉呀妈呀,累死我了,先写这么多了,奶奶的
